IELTS Summary Completion: method, traps and practice
A paragraph-length summary of part of the passage appears with gaps, and you fill them either with words lifted from the passage or with options from a boxed word bank. The summary is a paraphrase of the source — same ideas, different words — so every gap is really two questions: where is this idea in the passage, and which word fits both the meaning and the grammar of the gap?
How Summary Completion is scored
One mark per gap. In the from-the-passage variant the answer-rules bite: exact words, exact spelling, inside the word limit, over-limit means zero. In the word-bank variant there are more options than gaps and you answer by letter, so spelling risk disappears and precise distinctions take over — the bank will contain near-synonyms and wrong word forms on purpose. The summary usually covers one section of the passage, not all of it, and its gaps follow that section's order.
The rules that outrank technique: word limits are absolute — an over-limit answer scores zero even when the content is right — hyphenated words count as one word, ALL CAPS is officially fine, and both US and UK spellings are accepted (misspellings of either are not). The full set, sourced and dated, is in the IELTS answer rules.
A three-step method that survives the clock
- Step 1. Read the whole summary first to learn what it covers and where its story goes — then locate that section of the passage. Summaries condense a stretch of text, not scattered fragments.
- Step 2. For each gap, decide the part of speech the grammar demands — noun, verb, adjective — before hunting the word. In the word-bank variant this alone eliminates half the box.
- Step 3. Match the summary sentence to its source sentence via paraphrase, choose the word, then read the completed summary back: every filled gap must produce a sentence that is grammatical and faithful to the passage.
The traps that cost the most marks
- Filling gaps from the summary's own logic without checking the passage — the summary is bait for plausible-sounding words the text never supports.
- In the word-bank variant, choosing the right meaning in the wrong form ("develop" where the gap needs "development"). The bank stocks both deliberately.
- Hunting the summary's exact words in the passage. It is a paraphrase by construction; search for the idea, not the wording.

Prompt: Passage: "Cork oaks are unusual in surviving the harvest of their bark, which regrows over roughly a decade. Demand fell as screw caps spread, and some producers abandoned their groves." Summary gap: "Cork can be harvested without ___ the tree, but cheaper closures reduced ___." Word bank includes: killing, killed, demand, supply, planting.
Approach: Gap one follows "without", so grammar demands an -ing form: "killed" is out on form alone, and "killing" matches the passage's "surviving the harvest". Gap two needs a noun that fell because of screw caps — the passage says "demand fell", so "demand", not "supply", which reverses the economics. Grammar eliminates first, paraphrase decides second; that order is the whole technique.

Questions learners ask
What is the difference between the two summary completion variants?
One variant fills gaps with words taken directly from the passage under a word limit — exact words, exact spelling, over-limit scores zero. The other gives a word bank with more options than gaps, answered by letter, where the traps are near-synonyms and wrong word forms. Check which you have before you start: the strategies differ.
Does the summary cover the whole passage?
Usually not — it condenses one section, and its gaps follow that section's order. Locating the right stretch of text first is the biggest time-saver on this type: read the whole summary, identify its topic, and find where the passage discusses it before filling anything.
How do I choose between similar words in the word bank?
Grammar first, meaning second. Decide what part of speech the gap demands and strike every option in the wrong form — the bank stocks "develop" and "development" side by side deliberately. Then settle the survivors by paraphrase against the passage, never by which word sounds better in the summary.
Can I use my own words in summary completion?
No. In the from-the-passage variant you must use the passage's words within the limit, and in the word-bank variant only the boxed options exist. A synonym of the correct answer — however accurate — scores zero, which is why this type rewards checking the source over trusting your memory of it.
